Journal ArticleDOI

Stardust Interstellar Preliminary Examination IV: Scanning transmission X-ray microscopy analyses of impact features in the Stardust Interstellar Dust Collector

Anna L. Butterworth, +69 more
TL;DR: In this paper, the authors report the quantitative characterization by synchrotron soft X-ray spectroscopy of 31 potential impact features in the aerogel capture medium of the Stardust Interstellar Dust Collector.
Journal ArticleDOI

Stardust Interstellar Preliminary Examination IX: High-speed interstellar dust analog capture in Stardust flight-spare aerogel

Frank Postberg, +79 more
TL;DR: In this paper, the results of laboratory hypervelocity impact experiments, during which cosmic dust analog particles (diameters of between 0.2 and 0.4 mu m), composed of olivine, orthopyroxene, or an organic polymer, were accelerated onto Stardust flight-spare low-density (approximately 0.01 g cm(-3)) silica aerogel.
Journal ArticleDOI

Mineralogy of four Itokawa particles collected from the first touchdown site

TL;DR: In this paper, four Itokawa particles collected from the first touchdown site were mineralogically investigated by optical microscopy, micro-Raman spectrometry, scanning electron microscopy (SEM), electron microprobe analysis (EPMA), and X-ray absorption spectroscopy (XAS).
Journal ArticleDOI

Stardust Interstellar Preliminary Examination III: Infrared spectroscopic analysis of interstellar dust candidates

Hans A. Bechtel, +71 more
TL;DR: In this paper, the authors used synchrotron Fourier transform infrared (FTIR) microscopy to detect organic matter in small particles within picokeystones from the Stardust interstellar dust collector.
Journal ArticleDOI

Stardust Interstellar Preliminary Examination II: Curating the interstellar dust collector, picokeystones, and sources of impact tracks

D. Frank, +68 more
TL;DR: In this paper, the authors discuss the inherent difficulties that arise during "ground truth" characterization of the Stardust interstellar dust collector, and provide a detailed description of the sample preparation techniques developed to address the unique goals and restrictions of the Interstellar Preliminary Exam.
